At the assumed 84 service calls plus four replacement jobs per month, this Michigan wage reference calculates approximately $15,740 mature monthly EBIT and $15,907 cash after maintenance before receivable changes. The minimum EBIT activity at the stated resolution is 63 service calls plus 3 replacement jobs per month (66 collected jobs at the exact mix). 20% less activity changes mature monthly EBIT to $4,989 in the largest of these one-input effects. Price, paid activity, nonwage costs and the delivery calendar remain planning assumptions. Results include the paid roster, before financing, income taxes and owner distributions.

Local residential HVAC service and replacement contractor with two paid field technicians, paid dispatch and owner-manager coverage, two service vehicles, ordinary parts stock, and a defined service area
State benchmarks: May / July 2025 · Page prepared September 15, 2026
The May 2025 state occupation medians price the same paid roster $240 per month below the national medians. Loaded payroll is $20,949 per month, including the assumed 18% employer-cost addition. This comparison changes occupation wages, not rent, achieved prices or paid demand. A wage median is a statistical anchor, not a hiring offer, legal wage floor or credential.

Paid hours and the employer allowance are authored assumptions. The preserved source record identifies workbook, sheet, geography and period.
At the stated contribution and paid roster, 63 service calls plus 3 replacement jobs per month (66 collected jobs at the exact mix) produces $2,301.01 mature monthly EBIT. At the previous activity of 42 service calls plus 2 replacement jobs per month (44 collected jobs at the exact mix), EBIT is -$11,137.99. This is the minimum at the stated 22-unit resolution; delivery still depends on the workload and collection checks below.
The reference month contains 84 service calls and four replacement jobs. Its exact 21:1 ratio can be scheduled in blocks of 21 calls plus one replacement, or 22 collected jobs. A weighted average invoice is valid only at that mix; an arbitrary count of generic jobs does not reproduce it. Each complete block uses 70.47 technician person-hours including expected callbacks, in addition to 30 monthly nonservice hours. Four blocks fit the paid roster; five exceed it. The reference ceiling of 98 is a continuously scaled mix estimate, while 88 whole jobs is the largest complete 21:1 mix under the same hour assumptions. Parts paid before collection have a separate cash load. A proportional sensitivity is an analytical equivalent until whole jobs and dated collections are reconciled.
20% less activity changes mature monthly EBIT to $4,989 in the largest of these one-input effects. The comparison below changes one input at a time; it is not a local forecast or a probability range. The 20% activity test scales the fixed mix as analytical equivalents; a proposed operating calendar must use whole service calls and replacement jobs.
| Test | EBIT | Cash after maintenance | Held-constant basis |
|---|---|---|---|
| Reference | $15,740 | $15,907 | Exact published input snapshot |
| 20% less activity | $4,989 | $5,155 | 70.4 weighted-mix collected jobs per month; same roster and other inputs |
| 10% lower net price | $10,364 | $10,531 | Direct-cost share held fixed; same activity and paid roster |
| 25% higher occupancy | $14,940 | $15,107 | $4,000 monthly occupancy; same other inputs |
| 10% higher wage rates | $13,645 | $13,812 | Same paid hours and 18% employer allowance |
Keep earnings and cash separate. EBIT deducts $2,367 monthly depreciation. Cash after maintenance deducts $2,200 maintenance capital expenditure instead, before changes in receivables. The funding scenario is approximately $358,601: $240,544 opening payments, $28,934 peak operating cash deficit and $89,123 retained buffer, with each displayed amount rounded separately. The buffer is cash held, not another expense or owner income.
Opening allowances, occupancy, price, cost mix, sales ramp and collection timing are reference inputs. For a selected address or service territory, validate the complete scope, paid calendar, supplier terms, applicable authority and dated customer receipts. Use the format-specific checks and source limits.
Published calculations support planning and education. They are not personalized financial, investment, tax or legal advice and do not guarantee costs, revenue, profit or financing. Confirm the requirements and commitments that apply to the selected operating plan.
The reference company uses two paid field technicians, paid dispatch and paid owner-manager coverage, two vehicles and a defined residential service area. Service calls and replacement jobs have different prices, direct parts and equipment, crew-hours, callback exposure and collection timing. The numbers below are authored planning inputs; the cited May 2025 occupation wages are the only geographic cost observations in this reference scenario.
| Revenue stream | Collected jobs | Revenue per job | Monthly revenue | Monthly direct costs | Monthly contribution |
|---|---|---|---|---|---|
| Service calls | 84 | $525 | $44,100 | $13,944 | $30,156 |
| Replacement jobs | 4 | $12,500 | $50,000 | $26,400 | $23,600 |
| Combined | 88 | Fixed mix only | $94,100 | $40,344 | $53,756 |
The shared reference calculator accepts one volume, price and direct-cost share, so this exact 84:4 mix is represented there as 88 weighted collected job-equivalents at about $1,069.32 each and 42.87% direct costs. This is a disclosed calculation adapter, not an observed generic HVAC ticket. Change the mix in the two-stream calculator, then recompute contribution and technician capacity.
At the fixed mix in Michigan, the model requires 62.23 weighted job-equivalents for depreciation-inclusive EBIT break-even, about 59.4 service calls and 2.83 replacement jobs together. Operating EBITDA is $18,107, cash after the monthly maintenance allowance is $15,907, and EBIT after depreciation is $15,740 at the stated mature volume. These boundaries differ because maintenance cash and depreciation are separate costs.
The fixed mix plans 311.88 of 346.67 paid field hours, including 9.48 callback hours and 30 support hours. The 98-job ceiling applies only to this mix. The shared model calculates receivables; customer deposits, $24,400 of monthly replacement equipment and variable-job outlay, supplier credit and inventory aging need a separate cash schedule.
Opening funding in Michigan: $358,601 under the authored vehicle, tool, stock, premises, roster, ramp and buffer inputs. For a selected territory, replace those inputs with current qualified-person, permit, vehicle, insurance, supplier, staffing, collected-price, job-mix and demand evidence. Build the dispatch and callback plan before promising more jobs.
This completed planning profile combines checked state wage and population sources with a transparent financial scenario. Use its opening-cost, operating-cost and revenue figures as planning inputs, then replace location-sensitive assumptions when evaluating a specific address or service area.
| Evidence family | Published basis | What to confirm locally |
|---|---|---|
| Opening costs | Published planning inputs — replace with local quotes | premises scope, fitout, equipment, installation freight tax, deposits, preopening training, opening inventory, contingency |
| Operating costs | Published planning inputs — replace with local quotes | occupancy, utilities, insurance, materials, payment fees, marketing, software administration, maintenance |
| Paid labor and employer costs | State wage benchmark used — confirm employer costs | paid roster, wages, wage floor overtime, employer taxes, benefits leave, workers compensation, owner role |
| Revenue and collections | Published planning inputs — validate price and demand locally | realized price mix, demand volume, capacity, industry cross check, launch ramp, seasonality, collections |
| Permissions and fees | Confirm for the selected address | activity address jurisdiction, initial fees, recurring fees |
National equipment prices can support the plan where configuration, delivery and taxes match the intended purchase. Confirm rent, selling prices, demand and permissions for the actual location instead of applying a generic state adjustment.
The Census estimate for Michigan is 10,127,884 people. It grew by 27,922 between July 2024 and July 2025 (+0.28%). This statewide movement cannot identify a viable service territory, collected job mix or productive field schedule.
Using the same paid roster, Michigan occupational wages produce $20,949 of monthly loaded payroll. That is −1.13% relative to the identical roster priced with national occupation medians ($21,190). Only wage benchmarks change in this comparison; it does not measure a state’s overall business attractiveness.

A local residential HVAC service-and-replacement company using two paid field technicians, service vehicles, ordinary parts stock, and a defined service area.
Two paid field technicians supply 346.67 monthly hours. The authored 84-service-call and 4-replacement-job mix uses 176.40 service-cycle hours, 96.00 replacement crew-hours, 9.48 callback hours, and 30.00 hours for training, stocking, and meetings, leaving 34.79 hours. The 98-job engine ceiling preserves the fixed mix; generic HVAC jobs are not interchangeable, and the figures are not observed demand.

Base wages total $17,754 per month. An authored 18% allowance for employer costs adds $3,196, giving $20,949 of loaded payroll. The allowance is a planning shortcut; it is not a state-specific payroll tax calculation or benefits quote for Michigan.
The research handoff's occupational wage rows are broad occupation anchors for the stated period and geography. They do not establish company-specific hiring quotes, qualifications, lawful scheduling, employer obligations, technician eligibility, contractor authority, refrigerant authorization, or compensation terms. The reference pays the disclosed field and support hours rather than using unpaid owner work to create capacity. Every operating role is paid, including management or supervision. If the owner performs a modeled role, their compensation occupies that role once; no additional owner draw is included in operating profit.
The middle 50% wage interval describes the occupation’s observed wage distribution. It is not a confidence interval for this business’s total payroll. Allocate the aggregate hours across an actual roster and check wage rules, overtime, leave and employer obligations for the chosen location.
| Use of funds | Cash paid |
|---|---|
| Two late-model used cargo vans and basic upfits | $90,000 |
| Service, diagnostic and refrigerant-recovery tool packages | $28,000 |
| Installation, ladder, safety and lifting tools | $12,000 |
| Opening repair-parts and consumables stock | $20,000 |
| Recovery cylinders, A2L storage and PPE | $8,000 |
| Small shop or yard setup and office furniture | $12,000 |
| Licensing, certifications, insurance deposits and professional setup | $12,000 |
| Dispatch, CRM, phones, website and IT setup | $8,000 |
| Launch marketing | $15,000 |
| Opening contingency | $25,000 |
| Refundable deposit (two months of occupancy) | $6,400 |
| Paid pre-opening training | $4,144 |
| Total payments before opening | $240,544 |
The equipment and premises allowances are the same in all 50 states for this operating format. They are a comparison baseline and must be replaced with local scopes and quotes. Training uses 120 aggregate paid hours at the modeled team’s weighted loaded rate. The refundable deposit is cash tied up, not an operating expense.
The cash schedule tests 60 months, with sales ramping through 40%, 55%, 70%, 82%, 90%, 96%, 100% of the volume assumption. Full payroll and fixed costs begin in month one. The reserve covers the deepest cumulative operating deficit plus the stated buffer. A buffer is retained cash, not spending and not part of project payback twice.
The public model must distinguish booked, earned, invoiced, deposited, and collected amounts. Customer deposits for undelivered replacement work affect cash timing but do not create a second sale. Equipment and parts paid before final collection, supplier credit, receivable days, refunds, warranty recoveries, chargebacks, and taxes collected for government retain separate schedules. Asset purchases are depreciated over 60 months for this scenario. No sale or deposit recovery is assumed at the end.
The assumed 84 service calls plus four replacement jobs per month produces approximately $15,740 mature monthly EBIT after the paid roster and depreciation. At the stated contribution and paid roster, 63 service calls plus 3 replacement jobs per month (66 collected jobs at the exact mix) produces $2,301.01 mature monthly EBIT. At the previous activity of 42 service calls plus 2 replacement jobs per month (44 collected jobs at the exact mix), EBIT is -$11,137.99. This is the minimum at the stated 22-unit resolution; delivery still depends on the workload and collection checks below. Additional starting cash changes the funding position; it does not improve contribution per unit or reduce the recurring operating boundary.
| Measure | Monthly amount |
|---|---|
| Revenue | $94,100 |
| Variable operating costs | $40,344 |
| Loaded payroll, including management | $20,949 |
| Occupancy assumption | $3,200 |
| Other fixed operating costs | $11,500 |
| EBITDA | $18,107 |
| Depreciation | $2,367 |
| Operating profit (EBIT) | $15,740 |
| Maintenance capital expenditure | $2,200 |
| Mature project cash flow | $15,907 |
EBIT deducts paid operating costs and depreciation. Monthly fixed costs plus depreciation ($38,015.99) divided by contribution per weighted-mix collected job ($610.86) gives approximately 62.233191 collected jobs at the reference mix per month. Amounts are displayed rounded; the calculation uses the full input precision. At the stated contribution and paid roster, 63 service calls plus 3 replacement jobs per month (66 collected jobs at the exact mix) produces $2,301.01 mature monthly EBIT. At the previous activity of 42 service calls plus 2 replacement jobs per month (44 collected jobs at the exact mix), EBIT is -$11,137.99. This is the minimum at the stated 22-unit resolution; delivery still depends on the workload and collection checks below. EBITDA operating-cost break-even is approximately 58.358895 collected jobs at the reference mix per month. Cash-after-maintenance break-even is approximately 61.960353 collected jobs at the reference mix per month, before receivable movement; it is not launch payback or owner take-home pay.
| Measure | Months 1–12 | Mature month |
|---|---|---|
| Revenue | $972,053 | $94,100 |
| Operating profit (EBIT) | $99,108 | $15,740 |
| Project cash flow | $95,274 | $15,907 |
Project payback occurs in month 22 in this reference schedule. It measures recovery of actual pre-opening payments from cumulative project cash, with no financing or owner distributions. It does not measure cash paid back to an owner.
Cancelled visits, open estimates, unfinished work, unpaid invoices, deposits for undelivered work, and callbacks can inflate the dispatch board without producing the contribution used by the model.
Service and replacement work use different direct materials, crew-hours, collection timing, callback exposure, and working cash. The weighted shared-model unit must retain its exact fixed mix and derivation.
